My ducati VR charging light glows (as opposed to going out fully) for between 30 seconds and over a minute after start up. My Dynon says that it is providing the normal voltage. Â
I am told that a glowing light is a symptom of pending failure.
If this is the case I need to change the VR. (I have a bandC VR on order and will have to remove my OVP because the bandc has an integral OVP) Â
I also have a John Deere VR which I bought as a spare. My question is about the connection of the JD VR
The ducati is as follows:
G - dynamo
G - dynamo
C - charging light 22awg and 12AWG to capacitor
B - 12 AWG to capacitor
R - 12 AWG Capacitor
Is this the correct wiring for the JD? (product of web research)
AC - Dynamo (equivalent to G)
AC - Dynamo   (equivalent to G)
L - light 22AWG - (equivalent to C)
B+ - Capacitor 12 AWGÂ Â (equivalent to B)
IGW - Capicitor 12 AWGÂ Â (equivalent to R)
Second question: I have a 12v 20AH AGM battery. I see from the web that the JD VR outputs a higher voltage than the Ducati. Is this an issue for my battery?
Thanks
Will

I doubt that. That 'warning' circuit is exceedingly
crude . . . I don't even recommend hooking the thing
up. ACTIVE NOTIFICATION of voltage abnormality
is your primary monitoring system. I'd ignore the
light.

Why not leave your current regulator place
until the B&C unit is installed.

What voltage values are cited? It's
unlikely that the JD will not be suited
to task but why bother?
